RAIL-ANCHOR.

Specification of Letters Patent.

Patented Dec. 19, 1916.

origlnal appllcation filed February 4, 1915, Serial No. 6,112. Divided and this application filed April 9,

' To wfwmit may concern:

THE it known that I, Joux M. Soon", a citizln of the United States, residing at Racine, in the county of Racine and State 6' of Wisconsin, have invented certain new and useful Improvements in Rail-Anchors, of i which the following is a. specification.

. My invention relates to a device for preventing the longitudinal creep of a railroad 10 rail, and the'principal object of the invention is to provide a device of the bolt type in which the tendency of the parts of the rail anchor to become loosened from vibration or other disturbing causes is checked and prevented. x

A further object of the invention is to provide a rail anchor which will be very light in weight without sacrificing strength or 'holding power.

A-further object of the invention isto provide a rail anchor which will be simple and inexpensive to manufacture. v 5], With these objects in view, the invention consists in the novel arrangements, constructions and devices to be hereinafter described 3 and claimed. This application is a division of my coending application Serial No. 6112 filed 5 ebruary 4,1915.

The invention is illustrated in the accompanying drawing which shows a rail anchor constituting a preferred embodiment of the principles of the invention.

Figure 1 is a fragmentary plan view of a.

rail and one of the ties on which the rail is supported with the anchor of my invention attached to the rail. Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1. Figs. 3 and 4 are views, in. perspective, of

the two elements of which the device is composed.

Like characters of reference designate like parts in the several figures of the drawing.

Referring to the drawing, the rail is indicated at A" and the cross ties at B.

The anchor is constructed as follows: C is a bar of metal, preferably steel because of its rcsilicuev, hich is shown as formed with an integral hook or jav D adapted to extend around one edge of the base flange of the rail. The, bar is'bcnt, for example, at a so that with the jaw D in engagement with the rail the bar stands for most of its length out of contact with the baseof the rail and Serial No. 20,283.

in an inclined position with respect thereto, that is to say, until it is engaged with the other member E of the anchor. The dotted lines in Fig. 2 show this position of the bar. The other element E of the anchor is preferably made of malleable iron and is formed with a slot F adapted to embrace the edge of the base flange opposite to that engaged by jaw D. The member E is formed on the under side with a recess G providing an inclined or wedge surface H adapted to be engaged by a wedge I on the bar C. The bar and wedge member are formed with bolt holes J, K, respectively, and the bar is drawn up and secured to the jaw member by a bolt L and nut M. \Vhen this is done the wedge I on th bar comes wedge surface H on the under side of the jaw member and a wedging action results which produces a transverse clamping stress upon the base flange of the rail. Any tendency of the nut to back off the bolt is resisted by the stress of the bar against th head of the bolt. Consequently the anchor will maintain a firm hold on the rail under conditions tending to loosen and make inoperative the ordlnary rail anchor.

One of the elements of the device, preferably the jaw member E, is provided with a tie abutting flange N which bears against the face of tie B. The jaw D of the bar C preferably stands at a. little distance from in contact with the' the tie so that the tendency of the rail to creep in the direction of the arrow (Fig. 1) is self checked by the cramping action of the anchor on the rail which a movement of a rail of this sort produces.

\Vhilc I have described my invention in a certain preferred embodiment, itwill be understood that modifications might be made without departure from the principles of the invention. Therefore I do to be understood as limiting the invention to the precise constructions shown and described except so far as the claims are specifically so lnni'ted. l

I claim: 7 1. In a rail anchor, a. resilient member ads.

the combination of pted to extend under not wish the base flange of a rail and provided with means for engaging one edge of th- -r flange, a. member adapted to engage wag;- osite edge of sa d base flange, and a or secunng the resilient member tothe other member so as to clamp the rail be tween said members and subject the resilient member to a bending strain.

2,. In a rail anchor, the combination of a resilient member adapted to extend under the base flange of a rail and provided with an integral jaw for engaging one edge of the base flange, a member adapted to engage the opposite edge of said base flange, and a bolt for securing the resilient n'iei'nber to the other member so as to clamp the rail between said members and subject the resilient member to a bending strain.

3. In a rail anchor, the combination of a member adapted to engage the edge of a rail, a resilient bar provided with means for engaging the other edge of said base flange and adapted to extend under the same with a downward inclination in the direction toward the other member, and a bolt for securing the end of the bar to the first named member so as to subject said bar to a bending strain.

4. A rail anchor comprising two rail enaging members one of which is resilient, and a bolt for securing said members together in clamping relation on the rail.

5; A rail anchor comprising two rail en-- gaging members one of which is resilient. and a bolt for securing said members togather in clamping relation on the rail, one of said members being formed with a tie abutting flange.

6. A rail anchor comprising two rail engaging members, one of which is resilient, which members are adapted to have a wedging engagement one with the other, and a bolt for secgxring said members together in clamping relation on the. rail 7. A rail anchor comprising a member adapted to engage the edge of a rail and formed on the under side with a wedge sur face, a: resilient bar provided with means for engaging the opposite edge of the rail adapted to extend under said rail with a downward inclination in the direction toward the first named member and provided with a wedge, and a bolt for drawing said bar up against said first named member so that the wedge on the bar engages the'ivedgin}; surface on said member.

8. A rail anchor comprising a member adapted to engage the edge of a rail and formed on the under side with a wedge-surface, a. resilient bar provided with an in tegral jaw for engaging the opposite edge of the rail adopted to extend under said rail with a downward inclination in the direction toward the first named member and nrovided with a, wedge, and a bolt for drawing said bar up against said first named member so that the wedge on the bar ongages the wedging surface on said member.

9. A rail'anchor comprising a jaw member adapted to engage one edge of the base flange of a rail and formed with a tie abutting flange, a resilient bar provided at one end with means for engaging the other edge I of the base flange of the rail'and adapte to extend under said base flange with its opposite end out of contact therewith, and a bolt which extends through said last mentioned end of the bar and through the jaw member 2nd secures said bar against said jaw mem- 10. A rail anchor comprising a jaiw member adapted to engage one edge of the base flange of a rail and formed with atie abutting flange, a resilient bar provided at one end with means for engaging the other e of the base flange of the rail and adapted to extend under said base flange with its opposite end out of contact therewith, and a bolt which extends through said last mentioned end of the bar and through the jaw member and secures said bar a ainst said jaw member, the bar and jaw me her being provided with wedgesurfaoes which cooperate to produce a transverse clamping stress on the rail base. a

11. A rail anchor comprising a, bar of steel, one end of which is in the form of a jaw adapted to engage one edge of the base flange of a rail and which is bent at a point 'beyond said jaw so that the bar beyond said point is oblique to the bottom of the aw, a malleable iron casting having a; lateral recess to receive the opposite edge of the base flange of the rail, a downwardly projecting flange adapted to bear Igainst a tie, said member and bar being formed with c'o-acting wedge faces, and a bolt adapted to draw the free end of the bar up against said member.
